I personally feel it is better to just grind out the lower levels and have 1 good weapon for every 10-15 levels, it is stupid to spend money on items at lower levels because the jump in item prices at level 55-60, mainly 60, goes into 300k+ for something decent, so I would save my money for something worth while later on instead of looking for something better every level, if you just play the game, the items will come to you so don't worry too much about them now, and focus on saving.
