I'm going to go beyond your question regarding specific brands and talk about MODELS of marker that are worth considering. Not sure what you're price point is, but all of these are worth a close look:
1. Dye: DM5 w/ UL Frame, DM7, DM8, DM9 (all available used for less $$ and serviceable by the manufacturer)
2. Eclipse: ETEK 1, 2, 3 and also EGO 7, 8, 9 (all available used for less $$ and serviceable by the manufacturer)
3. Empire: Mini, Axe
I have never used Bob Long markers, so I cannot comment. They have always struck me as a bit of a gamble since they seem to use different lube (Dow 55 verus Dow 22) and need pressure testers, etc., to be set perfectly. Plus BLAST is a smaller outfite than the "Big Three" above. Good luck.
