Well, I have 4 sentinels on the way and should be arriving at some point. Got them for around $10 on ebay. Got sniped pretty good from a lot of stuff on there last weekend. I'm not sure if that's good or bad, because I could've gotten the Thunderbolts out of the way potentially. I like Forgeworld's models a lot more, but they cost double. I don't think I can start off getting them. I don't mind spending a little extra to finish off an army, but it seems like a bad precedent to set.
Forgeworld does have a lot of cool models though. Their Manticores look a lot better, as do their Hydras. Probably will be getting both from there, as well as Basilisks and maybe Chimeras (depending upon my budget).
