I don't think you can make one for that price but if you're buying it for investment, it will always be a repop sign worth abouth what you paid for it. The price is probably about right as long as its done pretty well
There's a guy on ebay that sells these. They're only 3' tall but the price is right. $200.00 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=380010826436&ssPageName=STRK:MEWA:IT&ih=025 His ebay name is signfeldinc. Kinda catchy !
the one on ebay is probably from China & they are very poorly done...it would be a laser print glued to a acrylic face which will probably let loose & the neon is garbage, you pay for what you get......
i make large hand painted neon signs also & i think the guy who is selling the 7' one is fairly priced.......
