One advantage of buying used is you can audition them in your home indefinitely (which IMO is the only legitimate audition), and if you decide you don't like them, just resell them and recoupe most/all of your investment. This is a little more difficult and risky with speakers that are large and hard to ship, so you need to be careful.
You should do your research so you're comfortable there's a hi likelihood that they will suit your room size, musical preferences, and will be compatible with other system components, etc. I would also try to locate speakers in closer proximity to home, so you can avoid shipping, or make sure the distance is short and cost is lower. If you find a local seller, they may also afford you an oppty to audition them in their home prior to purchase. Also, the archives contain many, many "speaker recommendation" threads that should be helpful if you search.

As for good classic speakers, I think there are many, many. I'm not familiar with Spikas but see mention of them often here. You may want to spell out more of your parameters (ie budget, room size, musical preferences, and will be compatible with other system components, etc.) here to entice recommendations.
