Dan: No need to save face, I know. I really wouldn't argue the reliability of any moped though. They're unreliable, cheaply made shitting things that, for the most part, work VERY well stock, but really don't hold up well to modifying. There are exceptions, but even on new stock bikes (Tomos in particular) things can and do break. Oil injectors, for instance. I know people that will give me the story about they've never had any problems, but for every one of those stories there are, like, twenty stories from people complaining that their 'peds broke. Like you, for instance, with a motor with 500 miles on it and bad electronics.
Mr. Madden 2010: I don't think it'd be a bad idea to buy a new Tomos. If you're willing to spend $1000 on a new moped, and really like how they look and ride, then by all means go for it. It'd perform better than your Suzuki by a long shot, you'll love having normal sized wheels, and it'd come with something very valuable: a warranty. Just don't void it by putting performance parts on, because if you do, you'd be better off buying something older, without a warranty, for a LOT less money. If you buy a new Tomos, you'd be wise to commit to keeping it bone bone stock, running oil in the injector, and taking it to the dealer for everything. Because if you don't take advantage of any one of those things, again, you'd be better off just buying an older one, saving a TON of money, and just learning how to maintain it properly yourself.
