questions about upgrading to a Dedicated server

[Supremo]

For the last year, i've been with aplus.net. the solo xr plan. not too bad at all, i have had no problems, 10 bucks a month, 1100mb and 45gb transfer.

Soon, I hope I will be at the point where I have to think about moving to a DS. I run a fantasy sports website, at the moment 100 users, but after a year of testing it all works (!) I have a major advertising blitz for the next few months coming, so fingers crossed that my user base increases, to 1000 or maybe even 5000

The easiest thing to do, I guess, would be to stick with aplus, and move to their 99 bucks a month dedicated server, with 1000gb of traffic.

Does anyone have any experience with Aplus?

Failing that, what others are there around the 100 bucks a month mark?

Netcraft has an analysis of domains moving from host to host.

Rackshack has gained a lot of hosts, But I wont go near them, I see that from other posts.

1&1 Internet has over 3 million customers, they have 500gb transfer DS starting at 50 bucks a month.
Any one have good or bad to say about them?


Also, I see a lot of reference to Plesk7. Good or bad? Essential or not needed? I foudn one hoster which was 59.99 a month, 20 bucks a month more if i wanted Plesk 7.


And one final question, about transfering a domain. Is it straight forward? What is the time frame when it comes from the switch from one host to another.

Thanks for all your help in advance. chosing the right DS is a big step. Until I cam here, Rackshack looked good, so I am gald i found you all. any advice is happily received.
