Reasonably priced and it WORKS!Keyspan by Tripp

Best one out there and a great price

Great Price - easy to install!

Good old Amazon came thru with a better price, and it was on my doorstep two days later.

For most applications, I think this is a nice unit, and well-priced when I bought it.

This was perfect to allow my to use my vinyl cutter with my laptop at a great price.

Well worth the price!

The price is high but some other cheapers ones do not always work..

Unit is fast and was actually Plug and Play and the price was right.

The Keyspan is a very good product for a very reasonable price

This particular USB to serial converter was recommended by Lionel, of course, available from them at an outrageous price.

After shopping around, I found the best price on Amazon.

The price is good

Great price and size

Awesome price and fast shipping

I knew looking it up on Amazon.com would be the most reliable source with the most competitive price
