Lately I have been thinking a lot about trying to learn the I:33 sword and bucker fencing method and before getting started I was wondering if steel bucklers are appropriate to use with wooden wasters. I have been thinking of getting a couple of the "round targe" bucklers from A&A and just want to see if people have experience with this product and if these would damage wooden wasters. Eventually I would love to buy an Albion maestro line sword & buckler sword to use for sparring and something like the Sovereign or Sherriff for solo drills but my budget is none too large. Any help would be appreciated.

You could also go the aluminum route for not much more:
