For me it would depend on what you want to do with the Apple II. If you like 6502 or 65816 assembly better or you want to play with GS/OS, or you have games for one but not the other.
I have a GS that now has a Focus card in it. The Focus, CFFA, or SCSI cards are probably better than the floppyemu for speed and flexibility, and the CFFA/CFFA3000 does neat things like let you mount/unmount images while the machine is running.
Apple IIgs stuff is not inexpensive. You have to kind of be really committed to the platform to want it. Even in the US where everything's most common, you "need", as has been said, a color monitor, some storage, an ADB keyboard/mouse (the older the better, apparently there are different ADB versions and the IIgs, even ROM03, only supports earlier ADB stuff. On my ROM03, I've used an AEKII without any problems, but I can't guarantee that will work on an 0 or 1.)
And then, you will want a RAM upgrade (because GS/OS and Teach will run with the ROM03's 1.25MB of RAM, but nothing else interesting will) and then you'll want storage. After all that, you'll likely want a CPU upgrade.
In all, I can easily envision spending $1000 on a IIgs. I got lucky because the system, 800k drive and monitor were all free at kfest. I got a Focus for $150 and a 4-meg RAM card for another $60 or so. All of the IIgses will use these expansion options, up to 8MB of RAM (which will require a better type of RAM card than what I have) and the 65816 CPU can be replaced/upgraded with a ZipChip or a TransWarp, which I am given to understand makes GS/OS and games a lot better.
For context: In total, you'll end up with something really slow and it will have eaten all of your money. It's really slow -- like, it'll be slower than a Mac LC.
The reason you get an Apple II series computer isn't because you think it'll be fast, it's because you specifically want the applications or you want to do programming or hardware hacking on it.
