I was all set to buy the Onkyo HT-S5400 HTiB from best buy and they pulled all the Onkyo products. I'm not sure if they sold out of everything or what. What should I buy? It has to be from best buy (have ~$300 gift cards). I'm looking for the best system for the money with the capibility to improve the system at a later date. I'm not opposed to buying just a receiver from best buy and getting speakers elsewhere. Are the newest models coming out? Is that why best buy stopped selling the 5400? Thanks.
