I bought a Daltech no buckle belt and it appears to be a great belt. The only issue I have with it is it's to big, but if I keep going the way I am I should fit in it by next year.
If you already have a little fluff around the middle, IWB carry, and go +4" to your pant size when ordering the belt, it will be too big. I ordered mine the same size as my pants and OWB carry with it without issue. IWB is too tight, so I stick with my leather Duluth Trading Lifetime belt. Expect that I'll get another Bio within the next year for IWB.
