Re: New computers
The aim of this report is {{U}}presenting{{/U}} (to present) the best {{U}} {{U}} 2 {{/U}} {{/U}}{{U}}choose{{/U}} for the company in replacing its computers in the central administration offices. Following some {{U}} {{U}} 3 {{/U}} {{/U}}{{U}}initially{{/U}} research, we narrowed the field down to three possibilities:
The first, DX590, is the {{U}} {{U}} 4 {{/U}} {{/U}}{{U}}more{{/U}} expensive of the three, {{U}} {{U}} 5 {{/U}} {{/U}}{{U}}with{{/U}} a cost of $590 per unit. However, it is the most {{U}} {{U}} 6 {{/U}} {{/U}}{{U}}powerfull{{/U}} and adaptable. The second, the HS Venturer, is a little cheaper to purchase, at $555, but has a smaller hard disk capacity and a slower processor. The third, the Songsing AF100, is {{U}} {{U}} 7 {{/U}} {{/U}}{{U}}the{{/U}} bargain at $480 and has similar specifications to the HS Venturer. However, Songsing is a relatively new company and thus it is difficult {{U}} {{U}} 8 {{/U}} {{/U}}{{U}}getting{{/U}} references for the product.
{{U}} {{U}} 9 {{/U}} {{/U}}{{U}}The another{{/U}} very important factor is the after-sales package. {{U}} {{U}} 10 {{/U}} {{/U}}{{U}}Every{{/U}} three companies offer between 1 and 3-year service {{U}} {{U}} 11 {{/U}} {{/U}}{{U}}garantees{{/U}}, but on slightly different terms and at different prices. The best of these is the DX590's two-year warranty, {{U}} {{U}} 12 {{/U}} {{/U}}{{U}}that{{/U}} is an on-site 24-hour repair service.
In conclusion, we recommend {{U}} {{U}} 13 {{/U}} {{/U}}{{U}}to purchase{{/U}} the DX590. The HS Venturer offers much less for a similar price, while the Songsing AF100 is probably too risky, because it has {{U}} {{U}} 14 {{/U}} {{/U}}{{U}}any{{/U}} track record. With good service back-up, the DX590 {{U}} {{U}} 15 {{/U}} {{/U}}{{U}}can{{/U}} also prove to be the most economical {{U}} {{U}} 16 {{/U}} {{/U}}{{U}}on{{/U}} the long run.
