Highly recommend it! The chips themselves aren't the cheapest but xvive and coolaudio are still cranking them out so you don't have to resort to tracking down NOS parts. Complimentary PWM from a microcontroller and a gate driver for the clock pins (the MN3205 has 2800pF input capacitance) and you're in business!

I'm always on the lookout for a deal on a space echo or echorec! Keeping them in working condition is not the easiest unfortunately, and it's tough to justify the real thing when incredible emulations exist (I highly recommend the Strymon Volante for scratching that itch)
