You can get a Tamron or Sigma macro or prime lens for under $100, but a Canon might be $200 and up. I personally really like the ultra sonic motors that Canon and Nikon use, because they auto focus extremely fast, never
any focus hunting even in low light. You seem to have enough budget to get decent lenses, so I wouldn't opt for third party lenses unless your budget won't allow it. Also, I haven't really looked much at Pentax or Olympus' lens offerings, so I can't comment on their quality.
I'm buying this lens
next, and then I will have enough lenses to suit my needs. But that's what they all say I guess!
Thanks for the advice. If you don't mind, I'd appreciate it if you'd answer a few (more) questions for me
If a camera has image stabilisation in the body (like the K20D) does that negate the necessity for it to use lens based image stabilisation, or do you need both?
Do all DSLR lenses have motors (for focusing presumably) or do some not? If some don't how do they focus? Does the camera focus them (using auto-focus), or is it done manually?
Why is ultrasonic a good motor type for lenses? Is it because it reduces vibration, or is it because it focuses faster than non-ultrasonic, or both?
Isn't it best to get in-camera image stabilisation because:
You can use any lenses that fit, even if they don't have I.S. and still get stable shots?
Lenses without image stabilisation are generally cheaper than ones without, so the extra cost up-front to get I.S. in-camera (if there is any) is reaped back buy spending less on lenses?
Thanks for your help! I appreciate it!

Wow, that's a beautiful shot! Shame about the lens flare (if that's what it is) but you can probably just edit that out, no? Otherwise it's really nice. Love the colour, clarity and composition!
