I'm looking to get into large format, most likely 4x5, and looking for any advice as to which camera/brand to go for...

I can't afford much (I just bought a hasselblad and am financially committed to the company for the next 30 years)... looking to spend between 0-$300. I'd love to get something handheld, versatile, and something that makes a great image. I see Crown Graphic and Speed Graphic on ebay for around $250, but have no idea what's good. Please help! Any advice is greatly appreciated. Thanks.
