Brian, as this your very first iaito, my recommendation is to buy one that suits you as far as length & balance, & not worry much at all about how pretty it looks. It's a training device, after all, & likely one that you'll outgrow as you progress.
I went the same route that Chikodan recommended somewhat in jest, & bought a nice custom iaito as my first katana. I'll admit that I still use it on occasion, but I've progressed over the years to a longer nagasa & nakago, a totally different tsuba style, & an overall balance that is considerably different than when I started. I rather expect you'll do the same.
It'll help a lot if you can handle the iaito before you buy it, Brian, especially if you have a knowledgeable friend along. Right now, without any training or experience, about all you can do is hold it & see if it seems too point-heavy, or overall too heavy to swing. Good luck!
