I have a second hand earlier version of the G0730, mine is G1008. Looks to be very similar to the G0730. I have had this for about 14 months. I think it does not take up much more space than the G0801. I would not find the G0801 too limiting in travel, especially in the knee vertical travel. A number of tools consume a lot of nose-to-table distance.
The G0730 is on closeout for less than the G0801. If a G0730 is available for less price, it will not take up much more space than the G0801 and will give you a lot more capabilities.
