Irvine and MVVS are two very good choices among many others. I've already got two .75 - Super Tigre and ASP - but if I were in the market for one right now, the Irvine would rank on top of my list. Only wish they make a .72 and .90 ringed.

Judging from your choices, you're looking at Just Engines, right? Their Irvine prices just got dropped. Looks like I'm running out of excuses to get that .53.
