Have the Browning Strike Forces and they are best bang for your buck IMO. I also have Browning black OPS and I wouldn't take another one of those for free.
Look at this site, great technical reviews on many TC's. They aren't as cheap as some sights, but you get a SIMM card plus and extra 12 month warranty'
BTW, The new 2015 Browning's had a software glitch early on (see post in Hunting gear section) but that has been fixed with a free update.
