If the Lanzar does the job for you with in your budget and serves it's purpose for the particular install, go for it. I like that the model you are looking at has top mount controls. Why must it be 100 watts per channel? Could you consider a lower power amplifier if it is of a high reputation brand to ease some of your anxiety about Lanzar? (Lanzar has not always been this way ) Also consider checking the classifieds here for options. Not to be self promoting, but you can get the Sundown SAX-50.4 from the SSA Store for blow out pricing at $200, if you can do with a little less power, but a great crossover network. This Eclipse is a good deal. Along with this Cadence, this Diamond, or this JL, or this Memphis, or this Audison. They are all under $250 and are from brands of good reputation, even though they give up a few watts to your desire. There are more options on ebay, and I am pondering selling my Orion 800.4.
