well what I do is:

123-reg run my DNS - I use their web interface to manage the few records 
I have set (changes used to take about 24 hours to take effect but seem 
to have been much quicker recently)

very straightforward for A records but I have found mail routing a more 
complex issue...

I point my primary MX records at my adsl connected machine and secondary 
MX records at 123-regs mail forwarders.

If my ADSL connection is down incoming mail is forwarded to my ISP's pop 
mailbox and I fetchmail it in later (or use webmail from work if ADSL is 
down for days)

Running your own DNS is easy enough for simple setups but the only 
advantage it would give me is faster changes (and I'd have to worry 
about secondary servers)

I used to have a secondary mail server that would queue mail for me and 
redeliver later - but the ADSL went down for a month (someone at BT 
knocked a card loose in the exchange). As I couldn't read mail sitting 
on the secondary server I was then stuffed.

This way if my connection goes down I can at least read my mail from 
work and download it at home later.

The downside is that I can't reject junk (spam, viruses etc) sent via my 
secondary MX - as I've fetchmailed it ...

(I can /dev/null it but I'd prefer to reject so that if there are any 
false positives the sender will get a non delivery message)

You don't need to dedicate a machine to serve DNS for a personal domain
- it's very low load and not worth the pollution generated
