You can use a 210 just fine. Cheap and excellent will be a tessar or triplet or optar of similar focal length. I really like the meyer trioplan for a triplet, but there are options. Tessars are really really good for sharp and moderate contrast. For cheap and variable softness, the wollaston meniscus at f8-11 will be very versatile. Part of the appreciate of the speed graphic is you can use so many lenses because the camera has a built in shutter. I use it on a tripod, monopod, or handheld.
