Fom my experience having enough altimeters to have everything prepped and ready to fly without having to move anything is really the best way to go. It is so much easier to prep things at home in the workshop or garage rather than out at the field. And a big weekend of flights can go sideways if your first flight crashes and you were planning on using that altimeter in a later flight.
While I have a wide variety of altimeters I've standardized on Raven's and Stratalogger CF altimeters. I like the small size and the low power requirements of both. I have several of Adrian's Powerperch's and mini-A/V bays as well as magnetic switches. Allows for use in small airframes without any sacrifices. I really like accelerometer based altimeters as well.
For many redundant flights I'll pair the Raven with a Stratalogger. They have been very reliable and I like the fact that they are completely different than the Ravens - if one set of circumstances fools one my hope is the other will still read the inputs correctly. I run the Ravens with 1S lipos and the CFs with 2S lipos.
That said I still have my RDAS from 'the turn of the century' as well as a variety of others, including an ARTS 2. They still are flown in older rockets that are set up for them. The RDAS has many dozens of flights and still works great.
As had been pointed out with the inexpensive options available it's almost a waste of flying opportunity to have to move and altimeter between flights. But each according to his means.
