As far as wood working tools (and some lightweight garden tools go) I use 18v Makita exclusively I've found the tools to sit nicely in that cheap but quality box and I'm a carpenter by trade so the tools get used daily. What I really like is the electronics in the batteries keep the batteries alive for years. They're extremely long lasting. Any 18v tools would be your best bet if you're looking for daily use, away from the power. Buy one more battery than you think you need and look after them (and any lithium ions [laptops, cell phones etc] by not running them empty if you can help it, and taking them off the charger when they're done, ie don't leave them cooking overnight.
Choose a contractor grade platform you like and stick with that, (dewalt, bosch, Makita) don't buy ryobi or that sort of step down, they don't last under hard use. With tools price is soon forgotten, but you notice quality daily. Having said that I won't buy festool because the price is too high for me to want to take them out in the rain and mud, If I had a workshop, I'd probably bite the price bullet and buy them or Mafel, because they are excellent.
If you don't need the portability so much then (like others have said) an expensive compressor will last forever and tools are cheap.
Sorry for rambling on, I hope you can pick something useful out of this.
