Besides Avent 4 in 1 food blender, are there other brands that are good?

Philips is probably another brand you can consider. Quite a number of my friends use their combined steamer and blender. Though not the 4-in-1 (http://www.philips.com.sg/c-p/SCF875_01/4-in-1-healthy-baby-food-maker#m=USP4), but they are happy with the steamer and blender. So thought you can consider this brand as well. :)

My friend uses the Tommee Tippee Explora blender. She loves Tommee Tippee products and this blender is no different :) I think you can get it on Lazada.sg. Alternatively, Amazon sells them too.
