I've worked with 2 sites hosted at godaddy - and in the long run just wasn't worth it.  I'm usually cheap enough and have an "I can do it" attitude - but have come to really appreciate they folks at PowerDNN.  Yes, they cost more... but quite frankly they are very fast, and their support is great and responsive.  It's the old addage "You get what you pay for".  And I'm willing to pay a little more to work & stress a little less!

DNN is hosted at MaximumASP - but I've got no experience with them - and I'm sure this site isn't on a shared server.  But they should be considered.

I've done work with a guy who hosted his sites ad ihostasp.net - and we weren't thrilled. Speed was kinda slow... I never had to use them for support - he always did.. but I think he ended up moving to PowerDNN to.

Thanks, everyone, for the detailed feedback, I really appreciate it.  I'm relieved to say that my client had no objections to moving off GoDaddy (and had only paid for 3 months of the cheapest possible package), so after some shopping we've decided to move the site to 3Essentials.com.  When the sales rep (not even the tech rep) gives me performance tuning tips for DNN, i figure I'm in the right place.
