It is fine to post links to auctions that interest you, but just remember that strangers may look at your posts- in other words, if you see something really nice, it is probably best to keep your mouth shut. If you want it for yourself, don't tempt others by calling attention to it.

That is assuming you can actually tell it is nice.

After a while you will be able to spot most junk. If a seller always has kilts available- and they seem to be the same ones- you can probably gauge the value of his wares by the prices they have fetched in the past. If you see something that looks authentically good, say from a seller who has outgrown it or inherited it from a dead relative, or who deals in good stuff, you can probably distinguish it from the chaff by certain identifying characteristics.

The first is probably age- if something is over 30 years old, it was probably not made in a sweatshop for the tourist trade.

The second is a recognizable brand name, such as Hector Russel, Kinloch Anderson, or one of the other main line highland outfitters.

The third is a little subtler, but after a while, you may be able to spot "nice" goods just by a general feeling you get when looking- the cut of their jib, so to speak. Most of the time, a good first step is to check the fiber content.

On the other hand, if you spot something that looks good, but is definitely not your size, it is only fair and generous that you pass it on, so the rest of us might have a shot.
