Recommend a Firewire Drive Enclosure - SATA Drive - Swappable?

[MitchJi]

Hi,

I think I'm going to get this drive enclosure:
http://www.wiebetech.com/products/RTX100...oductspecs
http://www.wiebetech.com/products/specsh...J_spec.php
RTX100-SJ -- (no fan)
* 1 TrayFree bay, external enclosure
* Affordable, sleek black enclosure
* Comes with a stand for vertical use
* Single eSATA port, Single USB2 port
* Up to 65 MB/s (via eSATA)
* Lockable bay with a key

The plusses:
$99 price
no tray (I will be using it with 4 or 5 drives which at $20 a pop adds up)
no fan
Minus:
no FW (I really wanted FW800) but I need to get a eSATA card anyway

The one remaining potential issue before I make a final decision is if I do this I will need to occasionally swap the eSATA cable to another enclosure.

How hard is it to swap eSata cables (the older SATA cables are like pulling teeth)?

Thanks (Again)!
