I went with a 10 " a couple of months back .. and was really giving some thought to getting the 12" instead .. both come in under the 1K budget you mention .. the 10 " while not overly heavy is a slight handfull to move around if you have to go to far.. Its 1250 mm length is a little friendlier to fit a sedan also .. that was the decider for me in the end the extra length
of the tube was prolly not going to get in my car without a major
wrestle .. best of luck with your choice
