I would agree with Wanda in maybe looking for complimentary or alternative goods within the same niche line of products. SMC is very heavily marketed and I would suspect that for the most part, it would be pretty thin margins making it difficult to profit from. This would be especially true via on-line selling.

There are some good alternatives available in a variety of similar verticals; although I will not dispute that SMC's marketing materials are very good.

Good Luck.
