Your question is frequently asked and is difficult to answer as there is no one "best" combo.
Owners will suggest you buy what they have and some vendors will push a particular line- for whatever reason.
What I usually suggest is that a prospective client choose a few machines they like- and then I tell them what I dont like about each of them ;)
The perfect machine for you will be the one which ticks as many of your "wants" within your budget and with the good gear, it really comes down to nuances- so its a personal decision.
My recommendation is that you approach a few sponsors with your list and see what feedback you receive. This will assist you to make the right choice for you. If you can manage to visit a sponsor for a demo and a chat, thats better still.
Please feel most welcome to call for a chat if youd like.
