Good web hosting with Interchange (or other robust cart)?

[bluecalx]

I signed up with Saturn Services after reading some good things about them but they've been giving me the runaround for weeks. They had Interchange and I was planning on using that as my company's shopping cart.. but now they tell me they're not offering it anymore. So I'm in the market for a new service.

I'd really like to have Interchange as my shopping cart. It seems like it has every feature I could possibly want. My company offers a lot of products and we'll have price breaks for large quantities and such. So the cart needs to be fairly heavy-duty. If there's another cart that would handle that sort of thing, I'd be interested in hearing about it.. and a good web host that offers it.


Basically I need a good, reliable web hosting service that offers Interchange (or an equally powerful cart). Any advice?
