thread... So I go looking for expensive stuff to buy to make good use of the 20%. I go thru several ideas - landing on two items. The first; I really needed:

My homemade Carbon filter just restricts the airflow too much for my Laser Cutter... Leading to Laser tube overheating.
I did a completed listing search and found similar for sold $450 so offered $649.99, shipped via Freight (listing said 200).

The second thing was by the same seller - and this is the thing I didn't *really* need... but I have a modern version of by a different vendor at work and love it:

Agilent Infiniium 54832D 1GHz WindowsXP Scope
I have an newish, low-cost Rigol bench scope ( DS1102E - 2ch 100MHz) I bought new a couple of years ago... It works ok and got the job done... but capturing waveforms was not very good and looked like arse.
Rigol Capture
The new scope has all the probes and Digital Channel probes which makes me think it's a good deal! Again, I didn't pay asking price - I did another completed listing search and offered them the lowest bid. $2400.
Now I have a new problem; I don't think this scope will fit on the top of my electronic workbench... so now I'm considering rackmounting the scope and using a wall-mounted rack like this:

but have concerns that it might not be deep enough. My plan is to wait until the scope shows up and re-assess the bench situation.
