Universal site tool

[CityOfSteel]

I am in the market for a universal site adjustment tool. I want to beable to adjust different brand gun that have dovetails (sig, s&w, glock, cz) front an rear sites. Here's the thing. Which is the best for the money not just the best, because i seen some nice ones for $600 bucks which is way over my budget? But with that said I am afraid of maring my frames and sites by using just any tool so what do you recommend. Are there any for around $50 to $100 bucks that are good? I like to tune my sites in much more accurately then i can with a punch.

Thanks for your help.
