The best starter tripod is the most expensive one you can afford. Otherwise you'll do what I did -
1. Buy cheap tripod for £30.
2. Realise it's crap and buy a slighty better one for £50.
3. Realise it's no better than the £30 tripod.
4. Spend £120 on a big, heavy, stable tripod.
5. Try walking 2 miles carrying big, heavy, tripod.
6. Spend £240 on a good, lightweight, carbon-fibre, tripod.
Total cost - £440, several blurry photos and a bad back.
Now, if I'd just bought that £240 tripod in the beginning I'd have been a lot better off.
