Ralph you get whatever your happy with the caveat being you get what you pay for. Read well what your getting. I do see a lot of online deals are of older design. Battery amp size varies too. Some tool brands are still even pushing Ni-cad kits like Dewalt and Porter Cable. I have my old style Makita 18V saw and drill but I don't use it much anymore and I was torn between upgrading to Li-on with Makita seeing I could buy an adapter for my older tools. And I really like Makita tools. But the new Fuel 7-1/4 circular saw needs only one battery opposed to Makita's two. Milwaukee has an 18V miter saw in production overseas that would be popular here too. I seem to remember Ryobi having released one years ago?
I went to Milwaukee last year and have no regrets. Like its been said warranty is 5 years and Milwaukee is out there right now looking to dominate the market.
I have a good amount of newer Milwaukee tools both 12 and 18 volt, FUEL and brushed and I'm hooked solid right now. 4.0 batteries are pretty much standard unless you buy a what's called a compact kit and there is a new 5.0 too. Milwaukee just came off of a huge holiday tool promotion and it will probably start up sometime again sometime soon. A lot time they offer either an additional bare tool or battery if you buy a kit. I saved plenty of money that way. I buy a lot of bare tool on promos and the most recent deal was buy a bare tool get a free battery. I have the Hepa filtered vac, the blower, and a lot of the LED lights. along with drills, impact drivers, and impact wrenches among others. My everyday favorite tools are the 12v 2462 impact driver 12 volt 2420 Hackzall, the 2457 3/8 drive ratchet and the 2590 12volt radio.
Anybody ever seen the drop test video on that radio? Gotta love it!

Do you believe it?
And that 2763 impact...what beast for a cordless. Though the 2655B is what I use most often at work to change trailer wheels. Where I work I need cordless most all the time. Remote signage, 4 barns...none with electricity, Running out 300 feet of extension cords is bull. 3 tractors, a whole bunch of attachments, 4 wagon gears (2 as hay wagons), and over 50 acres of grounds. With all the junk tires they use flats are inevitable part of life.
Multiple torque settings with the FUEL impact tools are a real advantage. 2 position on the 12v and 3 on the 18v. Single setting impacts are fine for hammering screws in wood but leave a lot to be desired for mechanical work. Milwaukee does have a 2 speed 18v brushed I/4 hex impact though. (I scored a whole kit for $89 with compact batteries on a one day sale at HD online)
The 2403 Fuel 12v drill is an awesome tool with the 1/2" metal chuck. It's fast, powerful, and heavy too but doesn't cut out as easily as the other 12v drills with the built in overload sensing. The 18V FUEL 2604 is the most powerful in the Milwaukee lineup of clutched drilldrivers.
Milwaukee has already stood by me replacing my heated hoodie under warranty probably didn't have too either and when the orange big box failed to honor a free battery promotion one email to Milwaukee customer service had me the battery in two days time.
I am impressed with some of the Bosch offerings though like the Bosch IDH182 18V EC Brushless Socket Ready Impact and Bosch wireless charging too, But pretty much most choose one tool manufacture's battery platform and stick with it. I have never been one to have multiple brands in use at the same time. Milwaukee also just released a 6 slot battery charger 3 12v and 3 18v
