They are currently selling on ANSgear for $995. So, if you think that's a good deal, then go for it. I highly suggest you check that the gun works before buying. (check bolt,air it up, turn it on, dry fire) You don't want to buy a lemon.
that's is an excellent price for a fulling working ego 11. You should make sure that is is excellent order before purchasing, but you should check the BST thread. The lowest I've seen an ego 11 go for was $600 (and that was a heavily used, but excellently maintained marker that got sold extremely fast). Most people are asking close to $750 for them, though they might go down more once the LV1 is more in circulation
