Query: good blender, but cheap blade assemblies require frequent replacement

I've owned my Kalorik blender for a year and five months. It does a decent job blending. It handles ice and liquids better than smoothies. However, there is a serious issue is with the durability of the blade assembly. I've already gone through two assemblies -- they rust very easily, even though I don't leave them soaking, and I don't ever put them in the dishwasher. The blender also runs very loudly compared to other models I've had in the past.The only way to purchase replacement blade assemblies is through the manufacturer's web site, and you can expect to shell out about $17.50 including shipping for a replacement. That's a lot compared to the cost of the entire blender itself.
