Have you tried growing paphs yet? Surely there is some local resource where you could get some hybrids (even offspring, like Michael Koopowitz or Chiu Hua Dancer) to practice with. Maybe the British Paphiopedilum Society can help you locate a mature sanderianum type.

Reality check: Flasks are not for the faint of heart. You really should develop a methodical competence in cultivating mature plants of a genera, before attempting deflasking similar seedlings. They require consistent nuturing and decisive and swift response to issues such as fungal invasions. In other words, they won't tolerate a lot of tinkering and if you aren't exactly sure how an adult would fare in your growing conditions, it will be a sheer stroke of luck to get one of the flasklings to bloom size.

If you absolutely must play with babies, get a flask of something cheap and easily cultivated, like phal hybrids. For around $20 USD, you can get a flask of phals that could potentially be ready to bloom 18 months later. With the other $105, you can get a few mature paphs that you can gain success growing and 2 years from now you will know whether you want to mess around with a flask of more fussy* paphs from Canada.

Good luck!

*Just guessing. I don't know if they are harder to raise, but there must be some reason that a species that was first recognized over 100 years ago is still more expensive and hard to find?
