The major issue is that 2-post rack rails are generally U-shaped, and have tapped holes.

Server rack rails are L-shaped and generally have square holes.

The vast majority of mounting rails I have seen in server equipment, in the last few years especially, will not fit because of the extra inside rails. Been there, done that, had to buy a real 4-post rack.

Is it really a big deal to spend $500 for the proper rack?

I do agree that some 4-post racks tend to be flimsier than the 2-post racks, but when properly assembled, any decent brand should work fine. Just make sure to double check the weight capacities.
