Yea, we were in the same boat, we bought a 36" press, the reason we added Preps since our Dynasrip only goes to 32". I really looked at all of them and Preps seemed to be the best of them, but it's not without it's quirks. It is no where near as easy to use as Dynastrip, to me, that is. I come...
We do have two of them and only use one. Both are the 32x32 size. Is yours the 32" or the unlimited? If your press was 32" or less, you could get by with the 32x32 Dynastrip just fine. I'd be willing to trade you both of mine for your large one.
We are using Preps. it seems to work OK. I am looking for the large version of Dynastrip, you wouldn't happen to have an extra dongle for sale, would you?
