Just incase the OP or anyone is looking at the jasic machines they look like rebranded escco ezicut, £15k with no THC and an extra £5k to add THC makes an xtreme table look like very good value, similar rail design to reduce moment loading on the gantry at the expense of only being able to easily load front and back, no issue with a 4ft table. The extreme uses rack and the escco ezicut/jasic uses leadscrews, I've never seen an ezicut run but the leadscrews look a pretty small diameter for a 4ft table and I would be concerned they would whip especially if they ever get bent after a crash, it also means you cant manually push the gantry , probably not that important though.
