Purchased my S-335 early last summer to replace our 15 year old stainless steel grill.  What a great upgrade, the S-335 heats up so much quicker and is much more substantial, everything about the grill feels like quality.  The assembly took about 2 hours but I was going slow to make sure I didn't make any mistakes.  The process isn't difficult and the instructions are adequate.  I definitely recommend the S-335 grill.
