sony A300 (with Live View) for twin lenses only rm22xx. i recommend dont go back on those old tech (without Live View) camera. all new DSLR now came with live view go without live view basically you are helping those manufacturer clearing their old stock

but if you think to have more and cheaper cost to expand in photohraghpy, Canon and Nikon will be "very very" cheap compared to Sony & Olympus DSLR.

Example: 1 unit of minolta 50mm f1.7 for sony fit selling at rm450~rm7xx, although it is depend lens condition, but if for Canon, "new" 50mm lens with warranty insane cheap so, what happen for Canon used lenses price, you can figure out on it besides, you will have more choice on Canon/Nikon to hunt for lenses. based on my last experience when i was trying to search for Minolta lens 50mm lens, the first 20 pages web i browsing at photomalaysia and AsiaShutter (sell n buy section), 90% lenses offered there are belong to Canon and Nikon, 5% acceesories, etc.

however,i am sony a300 used here no regret i think your brain now its poison indicator in this condition:

Canon 30%
Nikon 30%
Sony 30%

So, make use your own 10%, and enjoy your new DSLR
