If you want to run the 2510, it is a great radio, and as it has already been said, to keep it alive send it to Doc, or Rogerbird and have them go through the radio to bring it up to snuff.
They have Known issues.
The caps are aging and need replaced, the glue used to hold many parts down to the main board and the CPU board is drying out on them and shorting/eating up traces/components and needs to be removed.
The Driver/Finals are no longer available.
The Displays are starting to show there age, you will see a lot of these radios now that there will be small "black" spots or "runs" in the corners or along the edges of the display.
These have no NOS replacements.
The ChipSwitch, the Ultimate replacement CPU for these radios is no longer available.
They require some work to get them to work good on 10 and 12 meters.
If you decide to go with a New radio, I would say go with the new 2950DX or if you want a High Power radio, the 2970N2 has been around long enough to get all the bugs worked out.
You get a Factory Warranty with a new radio.
It has more frequency coverage than the 2510/2600 out of the box, it has offsets for working repeaters, a bigger display, and it is a new radio, not a 30 year old radio.
The one I have in my truck now is a great radio, and is holding up well to rough usage.
I have not used the New Optima, but the are getting very good reports.
The 2510/2600/Lincolns are good radios, but the fact is that they are getting old...
