The Launch Pad makes both the MIM-23A (two sizes) and the MIM-23B.

These can provide for you a basis from which you could detail out to your heart's content! I do like their kits, but these are 'builders kits.' Gordy can make you the decals, too.

ERockets sells Launch Pad kits; I see them on EBAY from time to time.

Hope this helps.
