Looking to purchase a set of multiplying bottles. I'am sure there are differences in the quality as I see variance in prices of these addvertized. What do you reccommend or suggest? Is there a real major difference.

There is no big difference in the quality. If you like the appereance of the bottles you may buy the set. However there are 2 x 3 of 6 bootle sets and 2 x 4 of 8 bottles sets. They are usually made in India but do not pay huge moneys. There is no big difference in the quality. The ones I saw are aluminium.

I must agree with mr.bart. He has seen my bottles. I have two different sets. One is made in Iran and it is 2 x 3 altogether six bottles and the tubes are soft. six bottles may be stacked together. So I have bought two sets and using 2 x 6 bottles, an incredibly big production. My other set is made in India from Uday's magic. It is 2 x 4 bottles but the 8 bottles does not stack together, the the tubes are also metal. Ther is no big difference about the quality.So just beware of the prices. I have seen the Indian bottles at the magic auction site at a reasonable price. A classical effect if you like it.
