Don't know if this is the correct thread board,Does anyone know a good site where I can buy the 5 the models from the 5 series and the movies?.
If you mean model kits, there's a bunch of sites. www.starshipmodeler.com has current stuff - TOS, Refit & E-B in 1/1000 scale. (I also sell conversion parts for creating your own ships from these kits. ) There's also 1/2500 scale versions (although I don't sell parts for those.) www.megahobby.com is also good, as is www.hobbylinc.com
The easiest way is to just go to Amazon.com and type in the model names. If they don't sell the models themselves, they'll get them from a distributor like Megahobby. Also keep in mind that many of the same ships come in different scales. The larger scales will always be pricier.
