Replacing the tap probably won't be too bad. Main pain points apart from the price will be getting it fixed in place - the nut can be hard to work with, involving awkward angles and cramped conditions - you will probably want a tap spanner which is one of those tools you hopefully only use once a decade.
Also if you get something like a Grohe tap, check the fittings because they won't be UK sized and you'll need converters. The tails are always either annoyingly short or annoyingly long.
