What about a Myford 254S the metric ones are cheaper than the imperial ones. Only secondhand machines now. Very happy with mine.
Nathan's brief included 'good sized spindle bore, perhaps 38mm'. A 254S misses that brief by 12mm 
I would allow slip on the 38mm requirement to be the owner of a Myford 254S, ways can be found to get around that requirement, unless it was an everyday occurrence.

Many moons ago when people paid me to evaluate competitive bids, before issuing tenders we carefully categorised Requirements as either Mandatory and Desirable. Failure to meet a Mandatory would be enough to reject a bid no matter how good it was otherwise.
Treatment of Desirable requirements was more complicated in that they were scored and weighted to establish objectively just how important they actually were relative to each other. By comparing the total weighted scores, it was possible to identify which bid best met the requirement. The system reduces personal bias and – because it is objective – the decision can be defended if challenged.
Nathan's question described his requirements as a 'wishlist', that is everything is desirable. As so much is up for grabs, it's tricky for the forum to advise because we can't tell what matters or not. Possibly before choosing a lathe, Nathan needs help refining his list of requirements. (Apologies to Nathan if he knows exactly what he wants and why!)
It's worth putting a bit of thought into requirements because getting them wrong can be wasteful. For example, if Nathan has a mandatory requirement for a 38mm spindle bore, then the excellent Myford 254S is not for him. On the other hand, if 38mm is a convenience feature, then it can be scored relative to other convenience features.
Apart from spindle bore the other difficult requirement in Nathan's wish-list is that Camlock chuck. As a mandatory requirement camlock severely restricts Nathan's choice of lathe. No problem with wanting one if Nathan will be constantly changing chucks, but a seriously bad idea if the Camlock feature is lightly used. It's because specifying camlock eliminates many good alternatives, cheaper and/or better lathes, which is undesirable because Nathan has restrictions on size, weight, swing and budget as well.
