From memory, it's got about 50,000 on the clock (I'd have to check to be certain and confirm), but I'm not sure what it had done before the board was changed.
I'm pretty certain WDP still do the spares kit for them, although it's been about 6 months since I had to buy some.
Some of the O rings etc. from newer Angels will fit it anyhow.
Spares kits are fairly reasonble (around £20). A decent service from a reputable angel tech will get it back on the road.
BUT, If your a total newbie make sure you have access to a decent set of allen keys and a person to use them, or someone to do a service, as they can be a lttile tricky for the un-trained eye. You also need a special tool kit to get at the internals if seals ever need changing in there.
