Yes: Zebra Systems in NYC. BUT I suggest you exercise caution when dealing with this firm, i.e., only pay them with a charge card in case they "lose" your order or find they can't provide the products as advertised. I've had a couple of unsatisfactory dealings with them. Another gripe of mine is that in the last three years or so they've bumped the price from $29.95 to $99.95. If you do a search on eBay for "timex,sinclair" you'll often find Zebra selling kits there, usually with a starting bid of $49, so you can save a lot by going that route. The kits themselves (I've built at least two or three) are great. They're not exactly identical to the original retail versions (no original Sinclair BASIC manual, Zebrafied assembly instructions instead of original) but they work, and one advantage is that the RF modulator (if you care to use it -- I don't) is UHF instead of VHF and provides a much cleaner signal.
