Antenna options and fitting of head unit

So, last night I finished up a radio harness for a Sony Xplod head unit which replaces my dying OEM Honda one. Put it in this morning and I have music again. But now I think I need to replace my antenna. I'll probably go OEM style one but was wondering if anyone has used something else.
Also, has anyone used the scoche (sp?) plastic fitment things sold at walmart? The Sony Xplod head unit needs more support to fit right. As of now the center console is out and the head unit is just sitting on the hump.
Thanks!

No sleeve as the radio is used. Do those radio install kits have sleeves? I'm sure they would right? I could always fab something up.
In regards to the antenna, I was looking more into different types, like those that run along the top of the windshield, or those shark fin looking ones.
