3) 1GB(1x1024) 677MHz DDR2 SDRAM (+USD 115)
4) 2GB(2x1024) 677MHz Dual Channel DDR2 SDRAM(+USD 410).
I think 2nd option would be the best. 3 may out of budget already and I think it is single channel. 4 would definitely exceed my budget too.
If you can get the x1400 (and it doesn't use hypermemory or anything like that) then option 1 would be a good choice (should be dual channel.... if for some reason it's not, then it is not a good option). If you go integrated graphics or if the x1400 does use hypermemory (or whatever it gets renamed to), then you should do option 2.
Option 3 would be slower then either option 1 or 2 (single channel, you're correct)
And option 4 would of course rock, but like you said, it's out of budget.
One additional option is getting the memory from someplace else... (not sure if newegg ships to HK, or if there is some other online retailer the would be good out there). That would of course be much cheaper than getting it from dell.
