There's been quite a bit of discussion on TBN about the 5003 series. I can't remember anyone not liking their 03 but I think that the folks who have bought them know before hand that they did not want or need 4wd, or maybe were willing to forego it due to price, did not want bells and whistles, and were OK with the gear transmission. I have had mine for a year, a 5203, and love the thing. It is a simple piece of machinery--going back to pre high tech days, and has all the power I need.
Also, if you get a loader, its not a quick park/quick detach, or whatever you call it. Taking off the bucket is a snap--I have two buckets and can get the buckets changed out in a snap, but the loader as a whole would have to be unbolted.
I use the loader a lot and if I were using it commercially, would want a differnet tranny, but am willing to live with the inconvenience of the gear tranny for my personal use.
Seems to me for the price its hard to beat.
My 2 bits.
