No matter how much they try to say differently, the Hydraulink is NOT a hydraulic toplink. It's a mechanical manual toplink. It provides very little improvement over the standard toplink and is spongy to boot. If you mount a DC power pack somewhere on your tractor, you can buy a real hydraulic toplink for around $225 with hoses. You'll have about $550 invested by the time you get this all done, but you'll have the advantage of a power pack that can be used for anything that requires low flow. These power packs are what are used on dump trailers to lift the dump bed. They are pretty darn big and require a lot of current to run. I run mine sometimes with one of those booster batteries they sell with an air compressor on them. Get a toplink with double pilot-operated check valve and it's a set and forget thing. You'll only have to run the power pack when you want to change it.
Understand that this is not the elegant solution, but it is about 1/2 the price of a factory remote. I'm suggesting this only because you asked for a suggestion and this is the only satisfactory alternative that I know of. It's not the best, but will work.
