^^ What particular problems have you had with the Lo Pro?
I do agree about the cost, you can buy a decent guitar for the price of a gold one

. When I was putting together my RG410 partscaster, I needed a 1986 spec Edge, which has some differences from later ones, namely a 41mm block. I got lucky and didn't pay much, but was sweating bullets for a bit (yes, I could've got a Schaller, OFR or GE1996T instead). I know what you mean, though I haven't had issues with mine (have another in addition to said 410), and things like intonation, nut pad and string lock bolts, which can wear out, don't need to be proprietary to work. If a saddle gets screwed up, sure, you need proprietary; and there seems to have been a period when the studs weren't cut well so guitars had trouble returning to zero, especially after pull-ups.
