I am looking to get an inexpensive grid tie inverter. I dont want something as cheap as the Chinese ones, but I dont want to break the bank either. Any recommendations? I am going to be between 1500-2000 watts.

If you live in the US or Canada there really aren't any legal grid tie inverters at that wattage range.
You would also need to get approval from your POCO concerning any grid tie inverter that is connected to their power distribution system. You might want to start by asking your POCO what they recommend. -
Microinverters are good for small systems, or the Fronius Galvo series if you prefer a string inverter. Anything grid-tie will need proper approvals to get sign-off by the power company, which is another reason to avoid the super-inexpensive knock-offs that you can find.CS6P-260P/SE3000 - http://tiny.cc/ed5ozxComment

Then design your system for that goal.
1.5-2kW is a very small system.
Why are you going that small?
At that size, microinverters might be the most cost-effective (while safe) choice.
But in your shoes I'd seriously look at whether that's the right size for you - or if you're better off doing 3kW+

The previous generation of SMA Sunnyboys are still being closed out at very low prices by some distributors. They are still very good units with dual MPPT inputs, but without built in internet capability however a much nicer display than the new ones.BSEE, R11, NABCEP, Chevy BoltEV, >3000kW installedComment

Roof space for solar modules?
Ground space for solar modules that are ground mounted?
I'm going to guess you meant roof space.
2kW would be only 6 of 325W modules.
That's a really small array.
That's only ~100 square feet of area, (less than the floor space of one room in a typical house)
I've camped in tents with more floor space than that.
Are you sure that you're really that space limited?Comment

String inverters will have a minimum number too (maybe 6, will definitely depend on the inverter make/model and the modules)
So I think microinverters (Enphase) are what you'll wind up doing.
Good luck.Comment

Whatever a homeowner decides to use based on their system pv wattage please make sure you follow all local codes and rules set down by the POCO and AHJ before you connect to the grid.Comment
