I think this is a very nice, crystal-clear introduction to metric spaces and basic point-set topology. For the topics it covers, I like it better than Munkres, and I find it much easier to find things quickly when I need them. And hell, if you're in the US, you can't beat the $5.62 price at Amazon.
I like this book. Munkres is good but this book is a gentler start. It has better intuition for people coming in without as much knowledge of analysis.
