Body Solid is considered a "good" brand. Pretty good value too. A couple of things to think about. If you have pretty decent calf strength and load it up, the thinner pads will cause it to be uncomfortable on the top of your thighs. Also, I ALWAYS recommend trying a calf raise out first.....they can have a different feel depending on brand, that some people might not like.
If you have the time, you might want to check out craigslist in your area and or keep your ears out if a gym is closing. commercial models are FAR superior.
