No problem for me. I'd buy a first rate rhythm machine or a great midi player plus a Vibes setup and continue to do my thing. Actually thought about doing that and if you think your TOTL arranger is expensive take a look at what the best Vibes cost these days! Mallet work was my forte when I was doing studio work in the 60's and 70's.

Then as as been posted above doing DJ work with a good laptop is also a great option.
