It's pointless to buy anywhere else. Best selection, best service, best prices. If they have what you need, there's no reason to buy it elsewhere. I bet you most of us would pass out of we walked into their warehouse!
i've made several purchases through TFsource in the past few months and i've been impressed with the organization of the stock and the care in their packaging. in fact i've recommended this site to my other transformer collector connections. keep up the good work
