1:£50 tripod light /heavy breeze ....don't extend to full height (unless absolutely necessary)hang bag from hook underneath.....solid as a benbo (and if you're going to spend a fortune I'd get a benbo....you wont want to carry it far but you'll never have a problem with camera shake)if you're using a manfrotto giotto or any other otto you'll have to do exactly the same...cos it's the weight that keeps it steady
2:Wildlife...if you're really going to take wildlife pics you'll be in a hide with a fixed focal length waiting for the animals to come to you
3:lenses...the cheaper end of a good quality range is more than adequate if you really can't get that background blurred enough at 5.6 and spot focus use gimp or photoshop to fake it.
4:If you're crafting a shot in manual you have plenty of time to work round the limitations of your kit or even turn those limitations to your advantage
5:there is no more reason for reasonably priced kit to let you down than expensive kit....you will miss shots with both
6:I have always had to pursue photography on a tight budget my kit (often very cheap third hand 'crap') has never let me down....bad shots (and I've taken many) have always been the fault of the operator and not the machine
I don't know what budget you have Nola I'm just saying you don't need to spend a fortune to practice and succeed in your photography.
Sorry Suffolk-cpl I'm not trying to turn this into an argument....but I do think you're wrong
