I'd recommend being vary cautious about a no-name cable that claims to be equivalent. Some of this stuff is out of China and doesn't meet the specs they advertise.
LMR-400 should not cost $1.29 a foot, as that website claims. I've bought it in bulk for 65 cents a foot. Some careful shopping around should get you close to that.
I'd really go with a known product. Since your radio will only work as well as it's antenna, cutting corners on the antenna system is a good way to increase the likelihood of disappointment.
For 1000MHz, you need to be careful on your lengths. LMR400, even the good Times Microwave stuff is going to have a fair amount of loss. In a 100 foot run, at 1000MHz, you'll loose 2/3rds of your signal to feed line losses. If your cable run is short, you'll do better. If you can afford better cable, and plan to do a lot of listening well up towards 800MHz, 900MHz, etc, invest in something like LMR600, 1/2 inch heliax or better. Installation is harder as that stuff is stiff and harder to work with. I've got a couple of 800MHz systems, and the smallest cable we use for even short (< 50 ft) is 7/8th's heliax. The other site uses 1 5/8ths heliax. Of course this is for transmitting, but your repeater is only as good as your receiver. If the budget is tight, you can always do what you can now, and upgrade later.
Belden 9913? Skip it. It's going to be worse than the LMR400, and it can be problematic stuff. The big issue with 9913 is that it uses a hollow dielectric that likes to suck up water whenever it can. Do a search on the internet, and you'll find plenty of hams complaining about the stuff and how they wished they'd installed better cable.
