The Deep Trekker is the best reviewed ROV Geo-matching. Read some of the reviews here:
"Overall, the Deep Trekker DTG2 is a well thought out and executed micro ROV based on a very clever design. Construction is top notch and rugged. Although it includes a one year warranty, I see no reason why, if properly operated and maintained, you wouldn’t get many years of service for your investment. Operating the DTG2 initially can be challenging, but eventually will become second nature. A few minor improvements would make this transition even faster and easier. For the price, you’d be hard pressed to find a better value hide"
