This is a very good topic! Well done Shane!
Theres only a few lines I'd love to eventually have all models of.
The first is the classic Lasonic range. I've got the original TRC-931 and TRC-975 (and a white i931, but I'm not going to collect the modern ones). I'm after the TRC-935, TRC-920, all the squared cornered 931 variations, and a few more of the earlier ones.
Another line I want to have all of is the upside-down National Panasonics.
Towards that end, and it's more of style choice than a manufacturers line, I eventually want to have all the classic onepiecers with fake wood sides. I've got 3 already (two Nationals and Sony Zilba'P) but having all of those together would be utterly spectacular.
Rock On.
