Andale Mono is no longer included with Windows either, I suspect a licensing issue. I see MyFonts.com has reduced the price to $320/- (!) now for all four weights.
Monospace fonts are plentiful, and lots of alternatives exist, both free and commercial. I find that searching Google for “alternatives to” or even “free alternatives to” will produce a lot of options.
Which option you find attractive and viable will be highly individual.
