I would just add to a previous poster's feedback.... I too have a Wadkin Bursgreen BER2. While basic (as noted, no tilt spindle), it is about as heavy duty a machine you can get into a footprint like it has. It is beautifully made (ductile iron table, not grey), hefty for its size (about 800lbs) and essentially matches the footprint of a standard cabinet saw like a Wadkin Bursgreen AGS10.
Bearings are substantial, but if needing replacement won't require a second mortgage or selling off of any step children. It has replaceable spindles, so you can add spindles of different sizes as needed (might bring down future tooling costs). Also they came in 3hp and optionally 4hp 3 phase and are set up for two speeds out of the box. With a VFD attached you could expand those speeds up or down by 50% without too much worry. Others here may know of others in this same category of machine, so there might be other options in the size/weight category.
I'm just a hobbyist and use my garage, so it's a perfect machine for me (mine has a power feeder as well). You can pretty much run everything but the most massive custom blocks... The only drawback for me is finding different sized spindles here in the States is basically impossible (all US ones came standard with a 1" spindle top piece... been looking for 1.25", 3/4", and stub spindle ones forever), but I doubt you would have that problem over there.
You are getting all good advice, so I'm sure you will end up with something excellent!
