I am a big Bowen fan I have maybe 30 pieces. Heres my take on it.
There are hit and miss pieces, look on eBay, the ones you see for 300-800 were hits! Below cost were miss. By cost I mean well below retail, as
almost any release can initially be had for less than MSRP on Bowendesigns.
What they look like on the website, is exactly what they look like in your hand.
QC is pretty good. Of the 50 or so I have owned I've only gotten 2-3 with factory paint flaws and they were very minor. For prepaints they are insanely good.
The scale is awesome, it shouldnt bother you. They arent as big as PF's, but have way more class than any HT/12" figs IMO. Im not saying they look better but because they are a solid statue vs action figure, the presentation is just different. 99% of his statues are perfectly scaled and display just right with each other, there are a few exceptions.
The range of characters is INSANE. The statues alone have so many obscure characters, start getting into minibusts and forget it. I recommend starting out with some characters or a team you really love. Or hero and his archenemy.
Busts are cheap but really great quality, and while alone they arent impressive if you pair them up with their full-sizes, or related character full sizes, you can get some great display action.
They hold value just as well as anything else. Ive never really lost money when re-selling. Just like anything else though if you buy something with a run of 5000 for $110 bucks dont expect to see $200 back from it.
The customer service there is great (Virginia) if you choose to buy direct. You can save some bucks on eBay but as we all know that can bite you in the ass once in a while.
Good luck!
