I think there are a few things you need to decide.
1. Exactly what features you would like.
- sliding table?
- is a tilting blade important to you
- do you use sheet materials where a scribing cutter before the main blade would be useful?
- maximum thickness you want to cut ( and at what bevel angles if any)
2. How much space do you have for the saw. Can you accommodate a floor standing saw.
3. How much work and effort are you prepared to do on a saw, I.e. would you consider a secondhand machine?
For secondhand, if it’s floor standing have a look at Wadkin AGS10 &12, Startrite 175 and 275, Sedgwick TA315 & LK.
A friend on this forum was looking to upgrade his saw a few months ago. I have a number of different machines (virtually all of the saws Ive suggested) in my workshop and after looking at them all he decided to buy a SCM Si15 after using my main saw.....a SCM Si15...he’s converted it from 3ph to 1ph and will accommodate it in single garage with other machines. In all, the machine and conversion will probably have cost around your budget. The SCM is a production saw, larger foot print than the others I’ve mentioned and weighs in at c750KG. But it will rip 5 1/2”, has a sliding table, scribe blade, will happily run all day every day, it’s extremely accurate and produces an almost planned finish.
