Finally opened mine, and he's good. No paint issues or anything on mine. Definitely a major improvement on the Universe version. The shoulders on mine are a little loose, but other than that everything locks into place nicely. Transformation is pretty decent - not too simple, not too complex. I'm glad I got him, but couldn't help but feel a little bit like "Is that all?" after reading some of the gushing praise he's been getting on teh interwebz...which is entirely my fault for getting my expectations too high.:( I was expecting something that would blow me away like, say, RiD Scourge, but what I ended up with was exactly what was TakTom was going for - a really solid, decently-sized, nicely-detailed, well-designed representation of G1 Prowl, no more, no less. He's been overhyped quite a bit IMO, but regardless of that he is a nice piece that's well worth picking up. Just be aware that that's all you're getting - a really good G1-style Prowl, very much the definitive Prowl but nothing more - and you won't be disappointed.:)
I voted 'Only if', as in only if 1: you can find him for a decent price (I got mine for $45-$50, but much more than $60-odd, $70 tops I think would be pushing it in terms of value for money) and/or 2: you're a fan of the character (which I sort of am).
