Deb, my Advice would be the Tomos...you can get parts for it more easily, and being that I live an hour from you, mechanical assistance would be ready to hand if need be.
The Kinetic has some quality problems, it's a solid, fast and hard running design, just that they require a bit more shakedown on purchase due to quality-control issues on the assembly line.
That and I am not so sure parts for it are that widely available here.
I'd stay away from the Avanti...any 'ped so rare even I have never heard of it is surely going to be hell to get parts and labor for, specially given what it would prolly cost if you did.
So bag yourself the Tomos, and if you do ever run into mechanical hassle with it, you will be able to get the parts, and buggin me to fix it for ya is a hell of a lot cheaper than payin some dork who's only worked on motorcycles $40-$60 an hour to fix it.
Let us know how it goes, eh ?
