Special Plarail Thomas?

That list is spot on TRA!
I’d round out the top ten with these...

6. Red Bulgy with service window
7. US T’nA James
8. Monty
9. Clear brown Annie
10. James works it out

*11. I am still on the fence about Buster and icicle Freddy.

There are rarer sets that require their packaging to leapfrog above these:
*Hector Greatest Moments w/red coach
*Donald & Douglas Snow plow set
*Powerful Gordon
*Diesel 10 & Lady Chase set

Got Monty, that's the only one. I've recently not been purchasing a lot of stuff as they either to for crazy prices or couldn't catch em in time.
