Few Questions before buying a new board

Hi guys,
I am going to buy a new board soon, but I just had a few questions. My parents are pretty cheap so I doubt they will get me a board over $250. I picked up snowboarding pretty quickly and will be going a lot more now (mainly freeriding).

1. Are Morrow boards unreliable/low-quality? I was looking at the House Boardshop and saw that all of the Morrow boards were less than $200.

2. Since my boots are size 11, would it be too risky to get a board that has a width of 25.00 cm.? I know that size 11 is categorized as wide/mid-wide, but I used the FrostyRider snowboard sizing guide and many of the snowboards that were recommended for a size 11 were only about 25.00 cm. wide or 25.2 cm.

3. At 5'6" and about 145 lbs., would a 155 board be appropriate? I am specifically looking at the Morrow Lithium 155 board: Best Prices on Morrow Lithium Snowboard 155 - Mens Snowboards Snowboarding Gear Equipment

Thanks.
