On Target in Pemberton (right in your back yard), and Top Gun next to Six Flags are both top picks. Nice fields, good refs, and generally good quality folk on the field. For strict woodsball Picasso Lake seems pretty good, though I've only played there once. The advantage of PL is that it is always BYOP, which can be nice. But they have good field paint, so either way, it's all good.
Hope to see you out there sometime, and welcome back to the sport!
PS: are you sure you need a new marker? I still play with a 24-year old automag, and it eliminates just as many people just as well as my newer Axe.
