Is $1,200 for a basic used 1050 setup for 223 a good deal?

If it's not worn out, it's a very good deal.

This^
Especially if the sizer is carbide.

I missed out on it by about an hour, saw it on craigslist this morning and the ad had only been up since yesterday evening. I'm guessing it was a pretty good deal.

Yeah, typically you see them for around $1400-1500 used.

Yup.  Jump on it.

I got mine new from Shootersproshop.com (known for blem noslers). Get on their maillist. They send out coupons now and then. I got mine during their 15% off coupon over the holidays. It was the last one (in 308). Since I knew I wanted to run a couple large primer calibers on it, I jumped on it. Like everywhere else, they sell at MSRP ($1740). But with 15% off and flat rate shipping ($12), you can't beat it.

Don't all you guys run over to shootersproshop because last I checked, they have very little Dillon left.

So, recently, I emailed them asking if they were letting their stock dwindle or if they were getting more back in. This was their response:

Good afternoon.

We will be restocking our Dillon selection, however, we do not have a time frame to provide you with.  Please let us know if you have any further questions.

Have a terrific day,
Shooter's Pro Shop

Anyway, they seem like good folks. I just have never gotten them on the phone. Stuff ships really quick. Hopefully they do get more Dillon product back in. I wouldnt mind a deal on a few conversion kits or heads.
