Hi Forbes,
I have the same one, Ive had it about 18 months now.
I'm only the average DIYer so it's not used on a daily basis, however for how much it costs I would say it's worth the money. Ive got the Dewalt 625 in mine and works really well.
It's nice height and the table is a nice lenth, and you can change the bits quite easily, and the fence is also very sturdy.
Even if you considered making your own (which I might through time) I think once you bought the track, fence, insert etc it would not be too far short of this price.
Only problem Ive had with it is that when moving the timber across it, it used the catch the measuring tape you stick to the edge, however I overcame this buying 2 cheapo steel rules from Poundland and routed them in flush with the table top and now works fine.
Hope this helps.
