Pretty much exactly as I said, but with more practical experience than I have.Yes, it does. It has a dual algorithm of DSAT and PZ+, both of which are less conservative than RGBM. The DSAT is the most liberal of the 2, but it gives the diver the choice. The problem with RGBM, especially the Suunto variety, is the way it calculates NDL over the course of multi-day, multi-dive trips.
I currently use an Oceanic OCi air integrated DC. Love it. And, yes, I have used and still own some Suuntos. The last Suunto I dove with regularly was a Vyper Novo. Nice computer with a large face, easy to read. I never had any problems with it limiting me to much shorter dive times than divers using more liberal computers, but then I mostly did trips that consisted of 2 dives/day for 5 days. With the SI that we had on those types of trips it didn't have a large penalty figured in, although it came close towards the end of the week. But I have had 2 Suuntos to crap out on me, a Gekko I got used with some equipment I bought that apparently the depth sensor flamed out, and a Vyper Air I bought new to replace the Gekko which then went wonky after 1 year. It was replaced under warranty with the Vyper Novo.
I switched to the Oceanic a couple of years ago and I can see a difference. On our trip to AKR 2 years ago, doing 3 dives a day plus a couple of night dives, I had no trouble with the DC putting me into deco. And that was diving air all week with depths exceeding 100 fsw on a few dives. Dive times ranged from 45 to over 60 minutes.
To meet the OP's criteria, I would recommend looking at the Geo 4. It has all the features he/she is looking for, is a wrist style DC, and comes in at under their price limit at 439.95.
I know what I know.
