Simped rudders, other fs hardware

Hi all,I'm going to build a system soon for FS9/X, I've been looking at hardware (rudders, yokes and throttles) and have a couple of questions.- There are 2 models of USB Simped F16s with different toe brakes - What is the difference between the "pressure sensitive" and "variable resistor" models?- Is the AETI ACFS-III the next step up from a CH yoke, or is there something in between I should look at? (The CH is about 100gbp, the ACFS about 500gbp - ouch)Are the CH throttles as good as the elite b200 quadrant? http://www.flyelite.com/hardware.php?product_id=17 - the elite quadrant looks sturdier (all metal construction) and is about the same price - are the two products comparable or is the CH in some way superior?Is it worth me getting a control board eg. irta flightboard http://www.aerosoft.com/cgi-local/re/ibosh...5674130,FS02168for FS9/FSX, and if so, which models should I be looking at.thanks.
