So, you like Tony's hey John?
Yeah, I love going there too. He has such a great selection. Email me if you ever want to come with me to my IPMS Club meeting.
Build22, I have built about 8 or 9 PST kits, and I've always found that they go together very well, and have nice detail. Their link & length tracks go on smooth, and the always have extra so you can really work on a good track sag! As Frasty mentioned, sometimes they mold in soft plastic, so watch yourself when removing parts from the sprues.
If you want to see pics of my PST models I built, let me know, I'll get them reposted here.
