Our own online warehouse has over 100,000 individual product variations listed in 18 parent categories.

So long as your systems (web server) and database can handle the load of search and service, the number of your products isn't really an issue.

Classifying those products well and presenting them to your customer in a way that they would think to look for the item they want, that is the trick.

Suggest you make your search very visible, and ensure your search engine is optimized well. Do you rely on a keyword search or all text search? (ie. Keyword field vs. everything). Depending on how your search is configured will determine how fast your pages are served... we found that out the hard way... :)
