I personally wouldn't pick them, I know the service would be reasonable because they're Entanet based but they put so little effort into their website that it gives the impression of not caring about their image. If you want an Entanet vISP then ADSL24 would probably be a better bet.
Fast.co.uk, Zen, IDNet, AAISP, O2, Be Broadband, Sky Broadband and a few others are also pretty good choices. It just depends on what your line can handle in terms of unbundled coverage and whether or not you're happy with a cheaper but longer term contract or a shorter and easy to escape but probably more expensive one.
