it is up to you- you know your budget, but you could get something that did the job for a lot less, or spend a fair bit more and get a lot more saw.
In terms of that machine, it will do the job. I would be tempted to look at the likes of Record, Axminster etc because they specialise more in that type of machine, and the support is likely to be better than machine mart, who typically wont know the first thing about them. I am not keen on Clarke machinery in general. In fairness the saw looks ok though.
I would probably look at a secondhand model. Ideally, a kity or an inca. There is a nice looking Kity as a buy it now on eBay in Bishop Aukland. There are no incas on there, but if you look at completed listings for "inca bandsaw" you will get a flavour of what is on offer.
