Tony,
Nice job on the first pen -- it turned out much nicer than my first.
You will be drawn into the pen-turning abyss, if you aren't already. Keep lots of kits and blanks on hand and don't be afraid to experiment a bit. And don't get too discouraged when you screw some up. You will, and that simply goes with the territory. Have some extra brass tubes for those times. Slimlines are cheap, around $2, and are great for honing your skills. The cigar pens are fairly easy too. Eventually you may want to step up to the next level kits like the Gents, etc. I've made a few of these, and the fit and finish is noticeably better. But I still enjoy cranking out slimlines. They're quick and easy and always a crowd-pleaser.
I've had good results from
Woodturningz. Their website leaves some to be desired, but they really shine in their phone sales. Really nice people who want to help you get what you want. They carry the whole Penn State Industries line, with prices a bit lower than PSI. Sign up for their email newsletter, as they have lots of sales.
Speaking of Penn State, they have a habit of buggering up orders. I've had 3 or 4 orders where I received the wrong item, or something was missing and yet the packing list said it was complete. Each time, a phone call corrected the problem, but be aware that their shipping dept. is sometimes off its game.
I've only made one order from CSUSA, but the service was great. Haven't tried Arizona Silhouette, but have heard many good things about them.
Cheers,
Kevin
