Old Olympus Zuiko Lenses for DLSR

Hi,
I've just joined and this is my first post. I've caught the photo bug quite bad. I had it about 30 years ago and bought an Olympus OM10 which I still have with a 50 mm and 28mm Zuiko lenses and a 90-230mm zoom plus a few filters. A couple of years ago I bought a digital Canon A95 Point and Shoot just for happy snaps. However, the happy snapping has developed into more of a happy hobby and I want to buy a DLSR. From looking at these websites and magazines it seems the serious hobbyists are predomonantly using Canon or Nikon DLSR cameras. Because I have old Olympus lenses I was thinking of buying an Olympus E510 or E520 with the kit 14mm - 42mm lens and also buying the conversion ring so that I can use the old lenses. I was wondering if people thought that was a good idea or not. The reviews I have read on the E510 and E520 all seem pretty favourable. The impression I get is that the Olympus might be slightly inferior in some areas to the equivalent Canon or Nikon but very good value for money. I have a budget of AUS $1000. The E510 older model is selling for just over AUS $500 on some online retailers. That would leave me scope to buy all the extras, memory cards, extra battery, tripod, bag, Photoshop etc.
So my questions are - Is it useful for me to have the capability to use the old lenses? My main interest is in landscape photography. Secondly, Should I buy the new E520 model or is the difference between the the E520 and E510 not large enough to justify the extra cost considering I am still a novice. Thirdly, should I scrap the Olympus idea and look at the Canon or Nikon DLSR models?
Thanks
Andrew
