Around 70 - 90, I'd reckon.
Personally, I think the 08 slg's are better than the 09 and UL's. Mine has always shot perfectly, and I've never had any complaints other than the flimsy plastic trigger (not that you really notice it when firing).
I've always enjoyed using mine and have never really felt like it's a bad marker. Don't think I'll be getting rid of it any time soon, even with my etek.
Give it a few upgrades (Clamping feedneck,a better barrel and possibly an on/off ASA) and it'll be a great starter marker.
