So I've been looking at these guys since I moved in 2008, and I think I'll finally drop some coin and give it a shot:

Aiming at the obvious: Wonder Washer and large ($150) spin dryer.
My thoughts here are, of course, the obvious: Summer wear Under Armour HeatGear, $25/shirt plus whatever for shorts. Your cycling t-shirts are pricey too. All in all you've got a base layer, t-shirt, light pants ... you're wearing $100 of stuff just to ride. Winter wear isn't much better. So a week's worth of cycling wear is going to cost you $500, yes?
But washing clothes every day is also expensive. So much water, electricity, and I live in an apartment and have to pay $1.25 to use the machine and $1.00 for the dryer! I sidestep the utility bills but that'd be like $11.25/week just for daily commute or $15.75 for every day. In a month and a half I'd pay off each extra set of clothes, so in about a year I'd have recovered my costs for just buying 5 sets of cycling clothes.
And ... here I am again, looking at this stuff. Maybe I could get 1 or 2 sets of cycling clothes and wash them every other day. That would make sense, it'd be convenient (I'd only need 1 set really).
Anyone do frequent washings? Or do you just have lots of extra clothes? Or do you keep a pile of base layers, and reuse mid layers for a couple days?
