I bought a Alex Duetto II from Chris Coffee. I was wondering if anyone has any insights on whether it's worth the effort to direct plumb it just to get a line pressure pre-infusion.

A plumbed in machine is much more convenient to use all the way around and the line pressure preinfusion isn't a bad thing either. When people come here seeking advice in this class machine, most of the time, I will toss in the comment about looking for a plumb in for ease of use. YMMV!!

Line pressure pre-infusion or not, direct plumb is the way to go. I can't adequately express the joy it is to pull shot after shot while using the hot water wand prodigiously to heat, rinse and clean cups with never a thought about refilling an empty tank or dumping an overflowing drip tray. I like my machine so much I wouldn't consider "upgrading" if I hit the lottery but if a catastrophe such as a house fire or theft forced me to consider another pumper, direct connection would be number one on my list of "must have" features. It would be way ahead of a fancy group head, double boiler, full auto, pressure gauge, PID or any other bell or whistle I can think of. Now that I've experienced direct connection, I would just use another brew method until I could save enough to buy another machine with that capability. I just could't go back to filling and emptying now that I know. It's like electric windows in an automobile, I could turn a crank but why would I choose to? The difference in price or difficulty in hook up is just not worth having to deal with a significant inconvenience every day of my life. I may not drive every day but I will surely drink coffee.

Not having to fill a reservoir (or eliminating a shot from being disrupted because you forgot) makes plumbing worth it. If you can also properly plumb the drain you will never regret the decision. It's been about 16 months since I plumbed mine and I do not regret it at all. I just have a three gallon jug for the drain and it is still wonderful. The benefit of preinfusion is that it tends to give more even extractions and lessens sprites. Whether it improves taste? You can decide that for yourself.
