cheapest adjustable dumbbells for sale

I purchased the XMark XM-3305 adjustable dumbbells in March 2011 from Bayou Fitness. I had considered other dumbbell sets, but these met our criteria: well constructed, inexpensive, attractive, and flexible.
Weights can be switched almost as quickly as selecting different weights at the gym. I checked the weights for 15, 20, and 25 pounds. The dumbbells are within 2% of the setting. Each dumbbell weighs almost exactly 25.5 pounds at maximum setting.
The labels on the product are cheap paper discs (look like cd labels) on each end of the dumbbell. I took these off immediately. The weights are actually better looking than the SelectTechs.
The dumbbells appear to be sturdy, and the mechanism for holding the plates on the bar looks almost infallible. The tray is a sturdy plastic that holds the unused plates in the proper position for reinserting the bar. When the bar is inserted into the plates, the motion is smooth.

Overall, I am very happy with these dumbbells. The design is good, I have no problem adjusting weight settings and can't foresee the weight changing pin failing any time soon. I also really like the esthetics of these, they are just cool to look at. I have large hands and the handles are comfortable for me. The only critique I have is if you look closely at the plates the finish could be a little better. I'm also a little worried they may begin to rust someday. I've only had them a few weeks and so far so good

I purchased these a few months ago. I was leaning towards the bowflex adjustable dumbbells and then saw these. I am very happy that I made this purchase. Of the bad reviews of bowflex...ALL of them dealt with weights falling off and coming close to hitting people. These weights seem to be held very firm and I haven't had any problem with them falling off or even seeming loose. I will probably get the bigger ones later on as my strength increases, but this was a good size because I use (most of the time) the full 25 and my wife is able to use them too with smaller weight. The look nice and perform how I would want them too.
