Great value for the Ebay cost  Time owned: 3 to 6 months
I used the 484B for quite a while and now have the 484C. Both work great, but with some reservations. The main drawback on both is that, with the 9V battery installed, if the power fails then the memories are retained for up to three hours and this can be extended by connecting a longer lasting source. However, if you have data stored in the memores and turn the keyer off, poof, you lose everything in the memories. This is explained in the Operator's Manual, so you just have to remember to leave the keyer on and all is great. It is incorporates an excellent keyer with speed/weight/tone/volume controls. Good value for the $ spent.
