Scope carts can either be expensive because the seller considers them valuable, or they can be given away for practically nothing because the owner no longer has room for them. A scope cart takes up a lot of room compared to putting a scope on a desk and scopes are getting smaller.
I got all of my Scope-Mobiles from the vacuum tube era and a 203 with
the TM500 shelves this way. Given how heavy the 500 series
oscilloscopes are, having a Scope-Mobile for each one is well worth
it.
Best place to look for one is at a ham swap meet. Around the time the swap meet is about to close the sellers get desperate to sell a cart, if they brought one, rather than haul it back home, so you have a lot of negotiating leverage at that point.
I got another 203 with my 7603 this way at the TRW swap meet in
Manhattan Beach, California.
