This is truly one of those, what are you doing things. True - taper attachment buying later may be difficult. Collet chucks are much easier and can be adapted from various sources. We bought a new lathe for work, "had" to have the taper attachment, never used it (going on 10-12 years). Depending on size of lathe, the top slide will let you do most tapers for short tooling projects. Rifle barrels is different. A better 3 jaw, set true style or not, may be a better investment. Collets are about setup speed with nominal sized material. Look at Joe Pie's collet video, he has some interesting things to say and may steer you in a direction. Accuracy can come from a 4 jaw just as easily. The QCTP would be high on my list as well. I don't have a DRO, but for similar bucks as a taper attachment I would say I would use it more.. I just bought a PM1340GT with all the better chucks - my philosophy was to cover the basics well, the rest would come (the less is more path). That is/was my take for the $ vs. features equation. But, again, depends on what you are doing or want to do and budget (that money thing just sucks sometimes). So to add confusion to the answer depending on budget - get a better base machine, get the QCTP, the DRO, the collet chuck,then the taper attachment would be my order of importance for my needs. Unlimited budget, get it all and have a well tooled machine to do anything you can imagine. We tend to be pretty fertile around here.
