A reseller is a good way into the business without too much outlay. However I found it increasingly frustrating as my supplier started good and then went downhill fast

I had a major problem with stability of 3 seperate reseller accounts and got increasingly fedup.

Being a Unix / Linux / Windows sysadmin anyway, I took the decision to move to a dedicated server so I could gain root access to my own system and make a fix without having to wait for my supplier (who wasn't fixing my issues).

It's a big challenge running your own box, but very staisfying. If you make the jump, make sure you can afford to run the box for a month or so before putting live accounts on it, then you can "fiddle" with no risk to you customers

I did consider building a box here in the office and putting a dedicated DSL line, but the costs (UK telecoms) were almost the same as renting a dedicated box in a proper DC
